答案與題解:
1.C 文章第一句就說到,由于地球起保護作用的臭氧層一直縮小,因此兒童發生皮膚癌的危險性增大,故C項應是最佳答案。
2.A 第三段第一句說,WHO在2002年的世界健康狀況報告中提到,全世界每年平均有S6, 000人死于黑素瘤及其他類型的皮膚癌,故A項是正確答案。
3.C 第四段最后一句說到,住在赤道附近的人更容易患白內障,并沒有提到南極、北極。至于膚色,該句說到,白人、黑人患白內障的可能性是相等的。
4.D 第五段最后一句舉例說明某些殺蟲劑、電冰箱及煙霧劑可能使用一些對臭氧層有害的化學物質,并沒有提到供內服的藥品,而且根據推理,也應將其排除在外。
5.A 短語for good或for good and all的意思是“永久地”、“決定性地”;英英詞典的釋義為“permanently”、“finally”、“forever”,故其他選項均不確切。
